As shown in the drawings, a main frame for the tractor is rovided comprising; transverse beams 0r liars conveniently of structural steel (channels are shown) and indicated from the front toward the rear of the machine by 1, Q, 3, and 4. Rigidly bolted or otherwise secured at the extremities of said beams and extending transversely thereof in parallel relation, are the side sills 5 and 6, which also may be of structural steel or any other suitable material. -Extending longitudinally the frame thus formed, and rigidly bolted on the transverse bars or beams 1, 2, and 3, are channels, the flanges of which are turned u wardly, as shown in Figs. 2 and 8, and w ich are arranged between the side sills 5 and El, and a distance apart equal to the gage of the wheels of the automobile to be used therein, that is to say, said channels are arranged a distance apart at centers equal to the distance between centers of the rear automobile wheels. Said channels at their front ends and between the transverse bars 1 and 2, comprise a straight portion Z, and the portion extending from the her 2, rearwardly to the bar or beam 3, curves downmcntary and SECLlOlllll view indicating a. Hat

wardly, as Shown, said downwardly curving portion being indicated by 8.

Extending longitudinally of the frame between the channeled tracks thus formed, are I-bcam bearing sills 9, which are secured on each of the said transverse frame bars and are spaced a distance apart sailicient to permit the brake drum on each rear automobile wheel to 98$ on the outer side thereof with sufficient clearance when the rear wheels enter the curved portion of said track. Slidably secured on each of said bearing sills 9, as shown in Fig. 5, is a sliding bearing comprising a hearing or box 10, provided on the under side thereof with ripping jaws 11, which engage beneath the :iterall directed flanges of the I beams forming said bearingsills. Rigidly engaged on each of said boxes 10, and extcndin rearwardly, is a rack bar 12, and journal in a bracket 1.3. rigidly secured nnthe inner side of each of said bearing sills, is a. shaft 14, provided with a, hand wheel 15, tonedjustlnent. On each end of SIUElSllflfli 1s a piniolz '16, which meshes with said melts on said boxes to slide the boxes on the sills. The automobile is backed into the tractor, the rear wheels tracking on the channel tracks 7. Said sliding! boxes 10, are moved forwardl by means of said hand wheel and shaft't'b the position shown in dotted lines in Fig. 5, to receive the axle, and thence moved rearwardly by the same means until the rear wheels of the automobile clear the downcurved channels 8, thus leaving the wheels free to rotate. A cap 17, is provided on meme/5 said boi; 1i), and a bolt, tail nut, or other suitable sccurin mams 18 is provided on the front end 0 the box and cap to secure the same in closed position after the axle is inserted therein.

Rigidlj' secured on the beams 1 and 2, as

between the front wheels of the automobile affording suflicient clearance on each side thereof for steering. They are provided at their front end with stir-raps or supporting straps 20, as shown in Fig. 1, which may engage over the front springs of the automobile near the axle thereof when the front end of the frame is elevated, as shown in F1g. l, or may he provided with U bolts 21, to receive the axle at theinner side of each spring, as shown in figs. 7 and 8.

An upwardly extcndingpost or strut 22,

is provided on each end of the frame bar 3, and is rigidly secured thereon and to the side sill members 5 and 6. Rigidly secured thereto at the top thereof and extending downwardly and forwardly and downwardly and rearwardly, are braces 23 and 24, which are secured respectively, the braces 23 to the transverse beam 2, and to the side sills 5 and 6, and the rear brace bars 24 to the rear sill and to said side sill in any suitable manner to afford sufficient ri 'dity.

' As shown in Fig. 1, a plate 25, a ords the rear connection and is riveted or boltedor otherwise rigidly secured to said brace bars 24, and to said sills and extends forwardly from the rear end of said brace bars and sills to a point intermediate the post 22, and the rear end of the frame and serves also as a brace for said rear brace member.

Journalcd on the top of said posts is the main.shaft or axle 26, of the tractor, we: tahly secured on which at each end the f are the broad faced tractor wheels 27, wliiiib are shaped as usual, and may have any tread surfece desired or preferred. Each of said wheels is provided with an internal r 28, near its perilbhery, as shown in igs. 1 and 7.- Journa ed on the brace bars 24-, and also upon brace bars 29, which extend from the rear end sill 4, to the tractor axle 26, is a jack shaft constructed in. two sections 30 and 31, held in elinement in said hearings and also by means of afsleeve 3Q, in which is rigidly secured the inner end of the shaft section 30, and in which the inner end of the shaft 31, is rotatably engjilged, as shown in Fig. 3. Each of said it sections is provided at its outer end with a pinion 33, moshing with the internal gear rented pins relation on the jack shaft by means of anysuitable clutch which permits said inions to rotate on the shaft when the clutc is re- Ieaped. For this purpose, any suitable clutch may be employed. A simple type of key clutch,however, is shown, in which akey 34, is secured to a collar 35, and isslidablf engaged in a suitable key sent in the jac( shaft. Said key is of suliicient length to permit the mine to be projected into a suitable key seal; in the pinion 33 as shown in Fig. 4. An adjusting ring 36, 1s rovided Do the collar 35, and in which salt collar rototes, and is provided with oppositely di- 37, in a familiar manne'r, which are engaged by the longitudinally slotted and yoked ends of a lever 38, fu'lcriuned on the side sill. the other end of which extends rcarwardly. A lever 39, is fulcrumed onthe rear end sill, and pivotally engaged on opposite sides of the fulcrum thereof are connecting rods 40, which extend laterally and at their outer ends are-engaged to theshifv inn levers 38 for the clutch. I

if referred, a low and a high 5 weed drive may afforded for the tractor. is is accognplished by providing two Internal gears 28-28, of different diameters in the tractor wheels, and providing: two driving, pinions 33 33, of suitable diameters on the shaft sections 31, meshing therewith. "When so arranged the key 34, is of a length to engage in the respective pinions at the opposite limits of its adjustment to commumcnte the drive t0 the tractor through either, as shown in Figs. 12 and 13.

Each of the rear nutomobile wheels is provided at the inner side of the brakcdrum with :1 double sprocket wheel rigidly secured thereto, as 15 usual with a single sprocket wheel in double chain drive machines, and

secured on each section of the pick sbaft'in alincment with the inner sproc col; wheel of each pair, is a sprocket wheel, as shown in Fig. sprocket wheels are trained sprocket chains 42, as shown in Figs. 1. 2 and 3. whereby the drive is communicated from the. motor to the rear wheels und thence to the jack shaft.

A belt pulley 43, is provided on the jack shaft section 31, and a set screw; drift pin or any other releasable means 43 is ro vidcd for engaging the inner end of the jack shaft section 31, in the sleeve 32, when it is desired to take the power from said belt wheel, thereby enabling the drive to be imported to sold belt wheel from both driving chains, though, of course, when using the machine as a tractor, said set screw, drift pin or other releasing mums is released or removed to permit differential movement of the Inch shaft Ht'ctmns wluch l8 compen sated us is usual in the differential gears on the automobile.

1, and about cocb pair of ulinod- The construction 'shown in Figs. 7 tell inclusive, is substantially the same in all particulars as that before described with the exception that the drive is imparted to the .wheels in advance of the center instead of at the rear thereof, and the driving connections are illustrated more particularly with reference to a shaft drive car. The frame may be identical in all respects with that before described, and also the hearings or sup orts on the bearing sills whereby the rear w iuels. of the car are elevated and sup-.

ported above the brackets therefor.

Rigiildly secured between the brace bar23, and t e sldesills 5 and 6, is a bearing -14, in

which is journnled p shaft 45, onthe outer 'endlofnrhich is rigidly secured the dri ing pinion 33, such as before described, and which meshes with the internal gear 28, in the-tractor wheel, a; shown in (tail in Fig.

10. Said shaft is provided on its inner end adjacent the frame with n sprocket wheel 40, on the inner face of which is rigidly secured a disk wheel or spider 47, of less diameter than the automobile wheel and carrying on the inner face thereof near its Jeriphery, clampse'mbracing a fixed. jaw '8, end an'inner movable jaw M) to coact therewith, and adapted to grip or engage the rim 49 or any portion of-the automobile wheel, as Shown, preferably near the periphery Clamping-bolts 50, are provided to draw said clamping jaws into gripping relation with the wheel to rigidly connect said shaft 4-5, in axiul-alincment with the rear axle of the automobile.

Journuled on the rear brace bars 24. is a shaft 51, provided at each end with u sprocket wheel in nlincme'nt with the s rocket wheels 46, before described on each side the tractor, and sprocket chains 52,

pro truincd about the some to drive said shaft 51. A bell: pulley "til, such as before dcm-ribcd, is provided on said shaft. Ina

lunch as the rear axle of the automobile is,

provided with a dillcrcntiol 53, as is usual, in dilfcrcntml 1 the shaft-bl, J5 not required. The operation was follows: dhc nutonur bile is backed into the vlanolior, the rear wheels of the car moving inwardly along the channel track 7 and 8. The bearing 10,

is, of course, first moved forwardly tothe position shown in dotted lines in Fig. 5, to receive the -automobile axle thereim and the box havingbeen'closed and secured in pny suitable manner, both bones (and, of course,

the automobile), are drawn rearwardly by rotation of the shaft 14, until the automobile wheels have cleared the track upon which previously supported. The front end ofthe tractor frame is then elevated and secured in any suitable manner betweenthe front wheels of the automobile, and, for this purpose, ma be secured either to the front ex 0 or to t e front springs or in my Ill suitable manner retained in such elevated position. If u chain. drive machine is used, as shown in Figs. 1 to 6 ihclusive, the sprocket chains driving to thepower shaft are now trained around their sprocket wheels and connected by any suitable master link, and the machine is ready for operation. If a. shaft drive nutomohi o is used, instead of a, chain drive, the connection, may, of course, be made in the mine manpier or the-driviu connection with the trueinacle directly from the.

tor wheels muv automobile axle or wheel to the pinion. In othcnwordsthe automobile having been drawn'into the tractor, as before described, and ad'usted with reference to the slimement 0 the shaft 45, the clam )3 are engaged with the wheels and the 0 mins trained about the sprocket wheels 46, und thus on the shaft 51. Of course, if preferred, the automobile wheels mi lit be removed and a suitable connection e ecte'd directly with the then exposed ends of the automobile axles. Having properly positioned and connected the automobile with the tractor, the operation of the machine for traction purposes is effected from the drivers seat in the automobile, as is usual. Of course, where the construction shown in Figs. 1 end 2, is used, the clutch lever is adjusted "to rigidly secure the pinions upon their-shafts. The machine may now be used for any of the purposes for which any tractor may he used, either upon the road or in the usual or on work for which a tractor may be employecli .Owing to the relative sizes of the pinions and internal gears and tractor wheels, :1. very great reduction of speed is afforded with consequent increased power and this en ables any and all the speed adjustments nud the reverse of the automobile to be used with the dune effect as ordinarily, excepting, of course. that the speed of the tractor shull necessarily be much less owing to the reduction before mentioned than in the case of the some speed adjustment of the auto mobile when not connected with the tractor.

Should it he desired to use the tractor upon soft c round as may frequently occur, a band wheel may be substituted on the front axle in lieu of the ordinary nutomobile wheels or any suitable spider 0 carrying a flut or other suitably shaped. broad rim 61 may be detachub'ly secured on the outer side of ench' front wheel to cover and to' extend around the pneumatic tire, as seen in Fig. 14. This is not necessary for road usennd ordinurilymay not be necessary for field use.

Vlheuit is desired to use the machine for other power purposes than for traction, it is only necessary, in the construction illustruLcCl in Figs. 1 to 5. inclusive, to throw the clutch out of engagement with the pinions and, of course, the some efl'ect may be attained by removing the not from shaft 45, to permit the pinion 33, to

1 from the shaft, thus disconnecting e f rive from the tractor Wheels, in either case permittingthe machine to be used for any power pu: 0883 transmitting the power from the belt pulley 43, by means of a suitoble belt.

The construction shown is exceedingly simple and coin aratwely megrpeuszve, as well as exceed ng y emuoimcul in operation,

permitting the automobile to be us'ed for the frame with any suitable bolt or coupling 55, topermit nttoc imcnt of such trams.

For the purpose of adapting the tractor for use with automobiles of different wheel bases, the bars 19. are connected with transverse beams I and 2, by menus of U bolts, which permitthe some to be ndjueicd longitudinally of the fume by shghtlv loosening the U bolts to afford adjustment. Of course, the U bolts are then set up again to rigidly engage said burs in adjusted position.

By affording a. low and u higigh speed.

the

drive for the tractor, as, for cramp e, shown in Figs. 12 and 13, a slow drive is alforded through the small pinion 33, for plowing, uf when heavily loaded or puilin loaded trams on the road, and o hig speed through the pinion 33", when not heavily loaded or with empty lrauns, these speed changes being effected. independently of the speed adjustment of the automobile trans mission and enabling the most economical fuel consumption to be secured.

Vvhilo we have shown a particular fruruc construction, it is to be understood that the frame may be vnricdin many particulars as may also the particular way of connecting the drive of the automobile ivith the tractor wheels for ufiordiug the power con motion for the belt pulleys. W's have shown but one of numerous arrangements which will readily be understood from the foregoing specification. and we purpose claiming broadly any nrrangement when, by an automobile and tractor attachment may be connected with an automobile and driven by the automobile power plant of whatsoever kind. l-Vc therefore do not pu 1' pose Hunting the patent for this mention otherwise than nccessituted bv the. pr or mi. as numerous detuils c-l construe 14. nun in varied without departure from the which pics of our invention.
